Abstract


OBJECTIVE: This study aimed to analyze the reporting and conduct characteristics of systematic reviews (SRs) published in dentistry by Brazilian corresponding authors and compare reporting characteristics of Brazilian SRs with the rest of the world. METHODS: A search in PubMed was performed to identify SRs published in dentistry in 2017 assessing different aspects of oral heath irrespective of the design of included studies. From this dataset, a subgroup analysis was performed considering only SRs published by Brazilian corresponding authors. Study screening was performed by two researchers independently, while for data extraction, one of three reviewers extracted details related to reporting and conduct of SRs. The completeness of reporting of 24 characteristics, included in the PRISMA Statement of the SRs classified as treatment/therapeutic, was evaluated comparing Brazilian SR to SRs from all other countries. RESULTS: We included 117 SRs with Brazilian corresponding authors. The majority focused on dental treatments (39.3%), with oral surgery (n=19, 16.2%) as the most commonly published. Included SRs presented varying reporting/conduct characteristics. Items such as use of reporting guidelines and screening method used were well reported. However, most SRs did not assess the risk of publication bias and did not use the GRADE assessment. Four (of 24) reporting characteristics of Brazilian SRs compared to SRs from the rest of world were reported statistically significantly more frequently: mention of a SR protocol, trial registry searched, screening method reported, and assessment of risk of bias/quality of studies. CONCLUSION: Reporting and conduct characteristics of Brazilian SRs are highly variable.
